Case ReportsPosterior reversible encephalopathy syndrome with Lilliputian hallucinations secondary to Takayasu's arteritis.
Posterior Reversible Encephalopathy Syndrome (PRES) is a rare complication of Takayasu's Arteritis. A 54-year-old, right-handed woman presented with Lilliputian visual hallucinations, postprandial abdominal pain, blurred vision and headaches. She then had a tonic-clonic seizure. ⋯ Risk factors for PRES include; pregnancy, immunosuppression, renal disease, hypertension and rheumatological disorders. Vasogenic oedema in affected lobes, most often occipital, is characteristic of PRES on neuroimaging. Prompt treatment of PRES can avoid catastrophic consequences such as death and can achieve complete resolution of symptoms and imaging abnormalities.

Case ReportsIdentification of perforated appendicitis within a right inguinal hernia sac (Amyand's hernia) by emergency abdominal CT scan: A case report.
Amyand's hernia (AH) is a rare condition in which the vermiform appendix is herniated into the inguinal sac regardless of whether the appendix appears normal or is inflamed. Most cases of AH are diagnosed intraoperatively at the time of inguinal hernia repair as its clinical diagnosis is difficult, and the role of computed tomography (CT) and other diagnostic imaging has not been described well in the literature. We report the case of a 79-year-old female who presented to the emergency department with nonspecific symptoms of nausea, vomiting, and constipation. ⋯ Complicated appendicitis in an AH is a surgical emergency, and an accurate diagnosis is necessary for proper triage of patients and appropriate management. CT plays a significant role in revealing an unsuspected diagnosis of AH. Radiologists must be aware of this rare presentation of the appendix in an inguinal hernia sac and be familiar with AH subtypes.
